Adding GitStream to CI on private repo

[echarrod]

We are running a GitStream image against our private GitLab repos.
Is there a way we can verify the config in MRs before merging?

I see there is a playground tool detailed at https://docs.gitstream.cm/gitStream-playground/, but this only works for public GitHub PRs.

Has anyone else got a solution that would work for private repos, to verify the config?

At the very least, we would like to be able to paste our config into a tool like the playground one, to verify, as I know CI might be harder to do
